This kit uses a single AA battery holder into which the user places a battery. LEDs then illuminate to show the remaining capacity of the battery. The circuit uses a quad operational amplifier to provide a reference voltage and comparators to determine which LEDs should go on. This makes it a great kit for studying operational amplifiers.
Testing of the kit can be performed using an adjustable power supply, or with our circuit tester (consisting of an AA battery holder, variable resistor & crocodile clips).
- Displays battery charge level with 4 LEDs.
- Great for showing how operational amplifiers work.
- 1 x PP3 Battery Clip Lead (Heavy Duty).
- 1 x 3xAA Battery Cage with Clip.
- 1 x LM324 Quad Op Amp.
- 1 x IC Socket 14 Pin.

Hi, My name is Mustapha. I am interested I purchasing one of your battery tester kits. I see that you have a circuit schematic, but was wondering if it also comes with a copper strip board layout diagram showing what it looks like on the board and actual connections, if not, will you be able to provide a one??? Please advise, the sooner the better, the quicker I can place the order. Thanks once again

The kit doesn’t come with a copper strip board layout diagram, and unfortunately we wouldn’t be able to provide a diagram of this either.
